Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
Flail Chest-II01:26

Flail Chest-II

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Muscles that Move the Forearm01:16

Muscles that Move the Forearm

The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

Summary

Proximal humerus fractures are common, especially in the elderly. Current evidence-based medicine lacks a gold standard for surgical stabilization, presenting an ongoing challenge in orthopedic surgery.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomechanics

Background:

  • Proximal humerus fractures are common, representing 5% of all extremity fractures.
  • These fractures are particularly prevalent in the elderly population.
  • Defining a gold standard for surgical stabilization remains an ongoing challenge.

Purpose of the Study:

  • To describe the unique characteristics of proximal humerus fractures.
  • To review current treatment strategies for these fractures.
  • To highlight the impact of recent advancements on surgical techniques.

Main Methods:

  • Review of clinical and experimental investigations.
  • Analysis of biomechanical and pathophysiological findings.
  • Discussion of the influence of new osteosynthesis forms.

Main Results:

  • No definitive "gold standard" for fracture stabilization is established.
  • Operative stabilization remains a surgical challenge.
  • Advancements in osteosynthesis, particularly locking implants, are influencing surgical techniques.

Conclusions:

  • Proximal humerus fractures require specialized treatment approaches.
  • Ongoing research is crucial for optimizing fracture management.
  • Modern implants are improving surgical outcomes for these complex fractures.
